Going to throw some money at a prime lens soonish, and I wanted to get any camera nerds opinions on athe two options I've got.

Been thinking of either the new(ish) cheap 35mm prime from Pentax, Pentax SMC-DA 35/2,4 AL.

The other, slightly more expensive option is an 85mm prime from Samyang: Samyang MF 85/1,4.

I think the quality of both lenses is fine and I've read good reviews about both, especially taking into consideration the prices. The gf has a 35mm prime for her Nikon and I enjoy that quite a bit. It's a bit faster than the Pentax at f1.8 and that attracts me to the 85mm. I see some great use of 85mm prime lenses on Flickr, but I'm a bit torn.

The 35mm is potentially a little more versatile, and is cheaper, but I wonder if the speed and focal lenth of the 85mm will allow me to be a little more creative. The 85mm also only has manual focus. Don't think thats a huge issue, but it's a small minus.

Stumped for the 85mm and so far so good. Manual focus is pretty tricky, especially at anything wider than f2.0 and especially especially if your subject moves, even slightly. The focal plane at 85mm and f1.4 is very thin.

Even so, some of the out of focus stuff that's come up has been kind of pleasing. Couple of examples below.

This woman turned her head very slightly and ended up completely out of focus. Still liking the result though.
